Inkjet printing apparatus and inkjet printing method

An inkjet printing apparatus comprising:

• a print head that has multiple nozzles configured to eject ink and arrayed in a first direction;
• a conveying unit capable of conveying a print medium relative to the print head in a second direction intersecting the first direction and in a third direction opposite to the second direction;
• and
• a control unit configured to control the print head and the conveying unit such that an image for a unit area is printed by multiple printing conveyance operations in which a printing conveyance operation for conveying the print medium in the second direction while ejecting ink to the unit area of the print medium and a printing conveyance operation for conveying the print medium in the third direction while ejecting ink to the unit area of the print medium are repeated alternately, wherein
• the control unit is capable of setting a first printing method in which an image for a unit area is printed by a specified number of the printing conveyance operations and a second printing method in which an image for a unit area is printed by a smaller number than the specified number of the printing conveyance operations, and
• the control unit sets the first printing method and the second printing method such that a time to be taken for one printing conveyance operation of the printing conveyance operations for a unit area in the second printing method is smaller than a time to be taken for one printing conveyance operation of the printing conveyance operations for a unit area in the first printing method.
